Using cattle salt-non food grade on a food production line

We are mainly a beverage concentrate and syrup company and we just started a product that has an ingredient that is not food grade (cattle salt) for animal attractant.  Is it allowed if the product is thoroughly cleaned after production before we start our beverage powder mixes?  I said no I don't approve, but I don't have the research to back me up.  Am I wrong or right?  Anyone have any FDA/SQF info that would support either?

i don't have an answer for you.  Since I'm sitting in the kitchen and my partner is here I looked up and said - hey, would the FDA (she has a lot of experience with the FDA) think an animal attractant is counter or see it as an adulterant or drug when made in a human food grade beverage company?  and she looked at me and said - OH MY GOD, NO - tell them NOOOOOOO!  Tell them to do it in a completely separate area.

Now, the only thing was she could not back it up with data - but I thought you'd like to know about that.
